Acquired in 1933 by Carlo Marchi, the beautiful I Collazzi estate is a jewel amongst Italy's many architectural jewels. Designed by Michelangelo, the original house was built on the ruins of a Roman fort and commands a view over the countryside unparalleled by any other in the region. Villa Collazzi is currently run by three siblings from the Marchi family – Carlo Marchi, Grazia Marchi Gazzoni Frascara and Bona Marchi Frescobaldi, The first vintage under the Collazzi label was 1999. The eastern side of the northern border of the Chianti Classico district runs through the Tenuta I Collazzi property. Of the estate's 960 acres just under 50 are currently planted to vines. The soils are composed of clay, sand and rock. The property is planted to Cabernet Sauvignon, Merlot, Cabernet Franc and Sangiovese. The estate produces a Chianti Classico called I Bastioni and a Super Tuscan blend called Collazzi.
